Going up for a perfume (6)
I believe the answer is:
ascent
'going up' is the definition.
(ascending means going up)
'a perfume' is the wordplay.
'perfume' becomes 'scent' (synonyms).
'a'+'scent'='ASCENT'
'for' is the link.
(Other definitions for ascent that I've seen before include "A climb or way up" , "Stance (anag)" , "lift" , "made by Hilary and Tenzing" , "Uphill journey" .)
